对于混合交通状况普遍存在的发展中国家来说，有必要开发一种异构交通流模型，该模型能够模拟所有类型的不同静态和动态特性，并且在计算性能上同样高效。为此，本研究采用了基于agent的框架，该框架采用队列模型进行移动性仿真。在第一步中，通过增加不同的车辆类型和不同的最大速度和大小来增强队列模型。此外，将传统的FIFO（先进先出）队列模型修改为更现实的改进队列模型，即更快的车辆可以通过较慢的车辆。讨论了交通流的基本图和时空图。
For developing nations, where mixed traffic conditions prevail, it becomes necessary to develop a heterogeneous traffic flow model which is able to model all vehicle types of different static and dynamic characteristics and equally efficient in computational performance. For this purpose, in this study, an agent based framework is used which uses a queue model in its mobility simulation. In first step, queue model is enhanced by adding different vehicle types with different maximum speeds and sizes. Furthermore, traditional FIFO (First-In-First-Out) approach of queue model is modified to a more realistic modified queue model in which faster vehicles can pass slower vehicles. The enhancements are discussed with their fundamental diagrams for traffic flow and spatio-temporal diagrams.
